Path of Exile 2's massive 0.5.0 "Return of the Ancients" expansion arrived on May 29, 2026, and at its heart is a brand-new league: Runes of Aldur. If you've been away or are weighing a return, here's a clear look at the league's signature crafting mechanic, the early patch fixes that followed launch, and what makes this update one of the most significant in the game's Early Access run.

What Is the Runes of Aldur League?

Runes of Aldur introduces a deterministic, player-driven crafting loop built around Remnants. In each area you explore, you'll find a Remnant that lets you craft an item of your choosing using Runic Recipes. The twist is that crafting isn't free — the Runeshapes you slot in determine both your reward and the difficulty of the encounter that follows.

Depending on which Runeshapes you use, activating a Remnant spawns a fight against tough enemies. Defeat them, and you claim the item you set out to craft. It's a risk-reward system that ties combat directly to itemization, rewarding players who can handle the encounters they create for themselves.

A Major Expansion, Not Just a League

Runes of Aldur ships as part of a much larger 0.5.0 package. The "Return of the Ancients" expansion bundles in:

  • A full endgame overhaul for Path of Exile 2.
  • Six new endgame storylines to chase beyond the campaign.
  • Two new Ascendancy classes, expanding build diversity.
  • A large amount of additional content layered on top of the league mechanic.

That scope is why 0.5.0 is being treated as a landmark update rather than a routine league refresh.

Opening Weekend: GGG's Priorities

As is typical with a launch of this size, the first days were about stability. Grinding Gear Games made clear that progression-blocking bugs in endgame quests were their top concern over the opening weekend, prioritizing fixes that kept players moving through content.

A wave of campaign quality-of-life improvements followed, smoothing out friction points that long frustrated players:

  • Farrow the questgiver now reveals the location of his objectives when you speak with him in campaign areas.
  • Singing Caverns: the siren direction mechanic was made more obvious.
  • Journey's End: a portal now links the boss back to the NPC.
  • Mechanarium: checkpoint wait times for power restoration were removed.
  • Halls of the Dead: permanent character boost locations are now easier to spot.

Balance and Crafting Tweaks

The early patch cycle also touched combat and crafting. Knockback was removed from the Tidal Waves runeshape mechanic, and Ore can be used to craft Pinnacle boss unique items — though some of those items initially rolled with incorrect item levels and were flagged for correction. These are the kind of granular fixes that tend to define a league's first weeks as systems settle into place.

Should You Jump In?

For action-RPG fans, 0.5.0 is an easy recommendation. A fresh league with a genuinely novel crafting hook, an endgame overhaul, six new storylines, and two new Ascendancies adds up to a lot of reasons to dive back in. The Remnant system in particular rewards players who enjoy shaping their own challenges, making Runes of Aldur feel distinct from the leagues that came before it.

If you're starting fresh, lean into the Remnant crafting loop early, experiment with different Runeshape combinations to learn the risk-reward balance, and keep an eye on GGG's patch notes — the league is still being tuned, and the meta will keep shifting as fixes land.
